Features

SAFETY

  • Large window openings to offer excellent visibility in all directions.
  • Safer access and egress with anti-skid upper deck surfaces and 3-point access to cab and machine.
  • Four corner oil-cooled braking system that provides excellent control, with service brake system actuated by hydraulic pressure and parking brake function that is spring applied and hydraulic released to ensure braking in the event of loss of hydraulic failure.
  • Operator Present System, which protects the machine and operator from uncontrolled machine movements, with hydraulic system neutralization and door sensor.
  • Safer service with service area located on cold side of engine, bucket control group safety pins, articulation lock and hinged belly guards.

OPERATOR COMFORT & CONTROL

  • Optional enclosed design provides fresh, pressurized, temperature-controlled air circulation with air conditioning.
  • Optional sound-suppressed ROPS cab for a quiet, secure working environment.
  • Controls, levers, switches and gauges positioned to maximize productivity and minimize fatigue.
  • Low-effort, pilot-operated joystick implement control with simultaneous lift and tilt functions to optimize operating efficiency.
  • Four corner oil-cooled braking system, which provides excellent control.

PRODUCTIVITY & PERFORMANCE

  • Loadrite Payload Control System, which gives the operator accurate, real-time updates on payload weights to help them reach maximum bucket capacities while reducing overloading.
  • Increased operator efficiency and optimized performance thanks to electronic auto shift transmission that allows operator to choose between manual or auto shift modes.
  • Transmission neutralizer that makes it possible for the operator to engage the service brakes and neutralize the transmission, maintaining high engine rpm for full hydraulic flow, enhancing digging and loading functions.
  • Fast cycle times thanks to optional ride control system, which gives operators confidence to travel at speeds above 5 km/h (3 mph) during load and carry operations.
  • Productivity-boosting hydraulic system, which delivers exceptional digging and lifting forces for fast cycle times, plus high hydraulic flow rates that provide fast response and powerful lift forces.

POWER & EFFICIENCY

  • Cat C15 ACERT engine, which provides unequalled lugging force while digging, tramming and traversing steep grades.
  • Torque rise that effectively matches transmission shift points for maximum efficiency and fast cycle times.
  • Torque Converter Lockup Clutch that combines maximum rimpull while in torque converter drive with the efficiency and performance of direct drive when the lockup clutch is engaged.
  • Mechanically Actuated, Electronic Unit Injection (MEUI™) high-pressure, direct injection fuel system, which electronically monitors operator demands and sensor inputs to optimize engine performance and fuel combustion.
  • Cat four-speed planetary power shift transmission matched with the Cat C15 diesel engine to deliver constant power over a wide range of operating speeds.

BUCKETS AND G.E.T.

  • Four dump bucket sizes that deliver unmatched productivity and structural reliability, featuring two types of cast corners to help strengthen the side plate to bucket lip joint and allow for various cutting edges.
  • Three types of Ground Engaging Tools (GET) available: modular weld-on, which deliver welded part reliability; Bolt-On-Half-Arrow (BOHA), which offer more wear material and feature a bolt-on design that enables fast and easy removal and replacement; and the Durilock Lip Shroud system, featuring hammerless installation and maintenance-free retention of GET, with three interchangeable shroud styles.
  • Cat Bucket Pro App, which provides real-time data on GET performance to help you plan maintenance, manage inventory and know cost-per-ton.
